Abstract
In the digital world the popularity and use of the Universal Serial Bus (USB) storage device is very vast. But USB needs a host usually a PC to initiate and mediate communications between two USB storage devices or USB sticks. It is not always possible to carry such a large size device to the particular location. So the system is designed which is more compact to carry anywhere. In this project, the file (such as .docx, .pdf, .jpg, .pptx, .avi) is selected from one USB device and transferred to another USB device using touch screen with display which provide ‘copy paste’ or ‘cut paste’ option. Also ‘delete’ option is available to delete the selected file and ‘cancel’ option is to cancel the operation. USB host controller (VNC1L) chip is used along with a microcontroller ARM LPC 2138 in UART mode. The host controllers consists two USB ports and are controlled through a microcontroller. This will eliminate the need of host computer and also saves power. This system is very cost effective.
